Terataspis

Terataspis is a comparatively huge, 60 centimetre long lichid trilobite genus from the Early Devonian, about 397 million years ago.

Terataspis grandis, like many other trilobites, was presumed to have been a detritivore that was also an opportunistic predator, preying on small burrowing animals, such as molluscs, worms, or arthropods.

The pygidium is large and shield-like with four pairs of slightly curved barbed spines on the sides.

The cephalon is characterized by its swollen front portion and longitudinal furrows that delineates a pair of swellings that located in line with the eyes.

The hypostome is almost flat and kidney-shaped and has a poorly defined central body.
